1990 Ford F-150 — Problems, Recalls & Complaints

THIS IS NOT A SAFETY RECALL IN ACCORDANCE WITH THE SAFETY ACT. HOWEVER, IT IS DEEMED A SAFETY IMPROVEMENT CAMPAIGN BY THE AGENCY. VEHICLE DESCRIPTION: 1990-1993 FORD F-SERIES VEHICLES EQUIPPED WITH DUAL FUEL TANKS AND 4.9, 5.0,5.8, OR 7.5 LITER GASOLINE FUELED ENGINES. SOME VEHICLES CAN EXPERIENCE A CROSS TANK FUEL FLOW CONDITION DUE TO A DAMAGED CHECK VALVE IN THE FUEL PUMP/SENDER ASSEMBLY. FUEL MAY BE SUPPLIED FROM ONE TANK AND SOME OR ALL OF THE UNUSED FUEL MAY BE RETURNED TO THE OTHER TANK.

Remedy: FORD IS EXTENDING THE WARRANTY FOR POTENTIAL FUEL CROSS-FLOW TO 12 YEARS OF SERVICE OR 150,000 MILES FROM THE VEHICLE'S WARRANTY START DATE, WHICHEVER OCCURS FIRST. THIS COVER WILL AUTOMATICALLY TRANSFER TO SUBSEQUENT OWNERS AT NO CHARGE. IF A VEHICLE ALREADY HAS MORE THAN 150,000 MILES, THIS OVERAGE WILL LAST UNTIL DECEMBER 31, 2001. IF THE VEHICLE IS EXPERIENCING A FUEL CROSS-FLOW CONDITION, DEALERS WILL REPAIR THE CONDITION FREE OF CHARGE.

UNDER CERTAIN CONDITIONS, THE SNAP RING THAT LOCATES THE PARK GEAR ON THE OUTPUT SHAFT OF THE TRANSMISSION MAY FRACTURE.

Remedy: INSTALL IMPROVED SNAP RING AND REVISED TRANSMISSION EXTENSION HOUSING.

A MALFUNCTIONING CHECK VALVE WITHIN THE FUEL PUMP ASSEMBLY CAUSES A PORTION OF THE UNUSED FUEL FROM ONE TANK TO BE RETURNED TO THE SECOND TANK. WHEN THIS OCCURS, THE CAPACITY OF THE SECOND TANK CAN BE EXCEEDED, CAUSING FUEL SPILLAGE.

Remedy: REPLACEMENT OF THE FUEL PRESSURE REGULATOR AND INSTALLATION OF REDUNDANT CHECK VALVES.

INCORRECTLY INSTALLED FUEL LINE CONNECTORS HAVE FUEL SUPPLY AND RETURN LINES CROSSED.

Remedy: REPLACE FUEL LINE ASSEMBLY.

THE IGNITION SWITCH COULD EXPERIENCE AN INTERNAL SHORT CIRCUIT.

Remedy: DEALERS WILL REPLACE THE IGNITION SWITCH.
